摘要： A battery operated device is equipped with one or more batteries each including a positive electrode, a negative electrode, a separator, and an electrolyte in a battery case. In this battery operated device, the battery has a gas vent that is opened due to an increase in pressure inside the battery case, and is configured to dispose the gas vent at a lower position thereof when installed in the battery operated device. Therefore, the battery function is ceased due to actuation of the gas vent.

摘要： A sealed battery includes an electrode group formed by winding or stacking a positive electrode including a current collector carrying an active material layer thereon, a negative electrode including a current collector carrying an active material layer thereon and a separator interposed therebetween. The current collectors of the positive and negative electrodes are exposed at an end thereof and the exposed ends are welded to current collector terminals, respectively. The active material layers formed on the surfaces of the current collectors are covered with heat resistant porous films, respectively. An end face of the separator is flush with or positioned inside relative to end faces of the heat resistant porous films. The heat resistant porous films have a melting point higher than that of the separator and have a thermal conductivity lower than that of the current collectors.

摘要： A safety mechanism for a laminate battery. An exterior case (5) consists of two molded sheets (5a) made of laminate sheets, superposed upon one another, and bonded together around the outer edges. The exterior case has a protrusion (10) that communicates with the interior of the exterior case and protrudes outwardly from one side. A safety vent (13) is made up of an exhaust hole (11) formed in at lease one of the two molded sheets (5a) in the protrusion (10), and a valve element (12) making elastic pressure contact with the edge of the exhaust hole (11) to seal it. The safety mechanism does not operate within the range of internal pressure variation during normal use, but operates reliably at a time point when a predetermined valve operating pressure is reached to release a necessary amount of gas to the outside, this valve operating pressure being within the safe range relative to the pressure resistance of the exterior case (5) made of laminate sheets. Also, the safety vent configuration enables a reduction in production cost.
